Tape media kiss-contact read verification

摘要

A supplemental module that includes one or more read elements periodically engages a magnetic recording medium, and the read elements generate an electrical signal corresponding to transitions written to the magnetic recording medium by a write element. A computer receives information representative of the electrical signal and determines if a quality metric of the magnetic recording medium derived from the electrical signal is within a defined range. If the quality metric is not within the defined range, a defined action is performed by the computer.

主权项

1. An apparatus comprising:
a supplemental module that periodically engages a magnetic tape recording medium; at least one read element in the supplemental module that generates an electrical signal corresponding to transitions written to the magnetic tape by a write element, the read element disposed a distance away from the magnetic tape when the supplemental module engages the magnetic tape, such that a signal resolution measurement value is approximately a minimum acceptable value when the magnetic tape is a reference tape; a computer that receives information representative of the electrical signal and determines if a quality metric of the magnetic tape recording medium derived from the electrical signal is within a defined range; and in response to determining that the quality metric is not within the defined range, performing a defined action.
